Book Description
Given that for centuries, the standard tool to understand diseases in tissues was the microscope and that its major limitation was that only excised tissue could be used, recent technology now permits the examination of diseased tissue in vivo. Optical coherence tomography (OCT) has promising potential when applied to coronary artery disease. OCT has the capability to identify coronary plaque and to distinguish between plaques that are stable and unstable. If the plaques are stable then OCT can direct percutaneous intervention (angioplasty or stenting). Optical coherence tomography is a light-based imaging technology that allows for very high resolution imaging in biological tissues. It has been first applied in ophthalmology, where it soon became the golden standard for the assessment of (epi-) retinal processes. The unique imaging capabilities have raised the interest of researchers and clinicians in the field of cardiovascular disease, since OCT offers unique possibilities to study atherosclerosis pathophysiology in vivo. With over 1.1M Americans having a heart attack this year because of unstable plaque rupture, OCT may have an increasingly important role in the early diagnosis of coronary artery disease. This unique publication offers the reader the basic background to OCT and its role in the diagnosis and management of coronary artery disease. The Handbook of Optical Coherence Tomography in Cardiovascular Research introduces the cardiovascular application of this technology. Clinicians, biologists, engineers and physicist are discussing different aspects of cardiovascular OCT application in a multidisciplinary approach. The handbook offers the readership a concise overview on the current state of the art of vascular OCT imaging and sheds light on a variety of exciting new developments. The physics, technical principles of OCT and its application in a broad spectrum of cardiovascular research areas are summarized by highly recognized specialists. The potential of OCT in peripheral and coronary arteries and in developmental cardiology are described. Each research area is introduced by a clinical expert in the field followed by discussion of different aspects from an engineering, biomedical and clinical perspective. Specifically, the current capabilities for plaque characterization, detection of vulnerable plaque, guidance of interventional procedures, Doppler-assessment, and molecular contrast imaging are being described. The Handbook of Optical Coherence Tomography in Cardiovascular Research targets researchers and clinicians involved in the field of atherosclerosis. The summary of basic physics, engineering solutions, pre-clinical and clinical application covers all relevant aspects and will be a valuable reference source.

Book Description
This brief provides a complete yet concise description of modern dive computers and their operations to date in one source with coupled applications for added understanding. Basic diving principles are detailed with practical computer implementations. Interrelated topics to diving protocols and operational procedures are included. Tests, statistics and correlations of computer models with data are underscored. The exposition also links phase mechanics to dissolved gases in modern decompression theory with mathematical relationships and equations used in dive computer synthesis. Applications focus upon and mimic dive computer operations within model implementations for added understanding. This comprehensive resource includes a complete list of dive computers that are marketed and their staging models, as well as a complete list of diveware marketed and their staging algorithms, linkage of pertinent wet and dry tests to modern computer algorithms, a description of two basic computer models with all constants and parameters, mathematical ansatz of on-the-fly risk for surfacing at any dive depth, detailing of statistical techniques used to validate dive computers from data, and a description of profile Data Banks for computer dive model correlations. The book will find an audience amongst computer scientists, doctors, underwater researchers, engineers, physical and biosciences diving professionals, explorers, chamber technicians, physiologists and technical and recreational divers.

Book Description
Deep Into Deco, Revised Edition has been fully updated to reflect the latest research outcomes. - Chapter summaries have been added to give a quick overview of each chapter. - A new section on nitrogen and helium kinetics has been added. - Av second appendix was added for calculating the acceleration in post-diving no-fly time associated with breathing surface oxygen. What makes this book truly stunning is that it is not only straightforward, easy-to-read and understand and free from technical jargon, but it also portrays the latest developments and controversial issues in technical diving. From the early history of experimental trial and error to the latest innovations and changes in the decompression arena, Deep Into Deco, Revised Edition brings the science into sharp focus. Throughout the book are demonstrations of how deco schedules are calculated in commercial software packages, without elaborating on mathematical equations or source code. Also, a grab-bag of additional points of interest that contribute to our current understanding of decompression theory is explored in detail. This book is a must read for any diver looking at understanding decompression theory, how it evolved, what it accomplished and where the latest research is heading.

Book Description
Underwater Physiology is a collection of papers that deals with the physiologically limiting effects of undersea, high pressure exposure ranging from fundamental biological reactions, through integration of physiological stresses, and to limits actually experienced in deep diving. Papers discuss oxygen, the mechanisms of toxicity, and the effects of oxygen on cells and systems such as its pathological and physiological influences in the neurosensory ocular tissue. Other papers discuss the physical effects of pressure and gases on cellular function, protein structure, and the possibility of alleviating symptoms through the administration of drugs. Tests in mice show that various gases exhibit qualitative and semi-quantitative differences in the characteristics of sickness, reactions to hypoxia, and the time before the onset of symptoms. A computer, programmed for nonlinear gas transfer and other variables, running in real time can compute directly from the breathing mixture and provide a real time solution to decompression sickness under various conditions. A combined therapeutic approach, recompression and dextran (an effective lipemic clearing agent) should be capable of treating decompression sickness in humans. Other papers investigate the influence of inert gases and pressure on the central nervous system, as well as, situations in undersea and manned chamber operations. This collection can prove valuable for physiologists, biochemists, cellular biologists, and researchers involved in deep sea diving.

Book Description
The biophysics of diving and decompression in the human body are complex. The average individual experiences atmospheric pressure swings of 3% at sea level and over 20% at altitudes greater than a mile. Divers and their equipment can experience compressions and decompressions in orders of greater magnitude than pressures outside water, all within considerably shorter time spans. The understanding of the mechanics behind diving is based on absolute pressure and pressure changes. While these mechanics are readily quantified in physics, chemistry, and engineering applications, the physiological and medical aspects of pressure changes in living systems need to be understood clearly to assess the safety of routine divers. This monograph is a compilation of a body of knowledge on biophysics, gas transport, bubble studies and physiological models used for diving and hyperbaric applications. Information in the monograph is divided into three parts that cover biophysics and models, data correlation and validation approaches and practical applications, respectively. The book is a useful resource for researchers and maritime professionals who wish to understand the biophysics behind underwater diving and decompression for the purpose of maritime operations as well as diving simulation applications.
